PADDLE-WHEEL.

SPECEFICATION forming part of Letters Patent No. 379,352, dated March13, 1888. A

Application filed November 10, 1857.

To all whom it may concern:

Be it known that l, Wnsrnnoron BRYANT, of Franklin, in the county ofIzard and State of Arkansas, have invented a new and ImprovedPaddle-W'heel, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement; in paddle-wheels, and has forits object to provide a wheel wherein the pad dlcs will enterthe waterwith the least possible resistance and leave the waterin a similarmanner, but in whiclnwhen the said paddles are in the water, they willpresent the greatest possible hearingsurf'ace thereto.

The invention consists in the construction and combination of theseveral parts of the wheel,as will be hereinafter fully set forth,andpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 illustrates a central transverse see- Fig. 2 is a longitudinalsectional View, partially on line a: :0 of Fig. 1; and Fig. 3 is aperspective view, partly in section, of the shift ing ring and collar.

In carrying out the invention the axle A of the wheel is mounted in asuitable frame, A, if used as a stern wheel, and when employed as a sidewheel in a proper outer frame and in the side of the vessel. In eachsupport of the axle and at each side of the bearing of said axle in theframe or ships side horizontal slots at a are cut in align ment with oneanother,and a ring, B, is secured to the inner side of said frame, orthe outer surface of the ships side, provided with outwardly-projectingthreaded pins 1) b, adapted to enter and pass through the aforesaidaligning slots a and a, respectively.

Upon the outside of the outer frame or support, A, suitable nuts, 0, areprovided the pins 1) b and screwed thereon in such manner as to admit oflateral play of said pins in their said slots. The pins, projectingthrough the side of the frame or support through which the axle extendsand where power is applied to the axle, are secured by suitable nuts toa horizontal sliding plate, D, which plate is provided with an elongatedslot, d, to receive the axle A, and

Serial No. 254,771. (No model.)

made to extend farther beyond said axle upon one side than upon theother. To this extended end d of the sliding plate D a vertical lever,E, is attached, i'ulcrumed upon a bar, F, secured to the ships side orto the inner surface of the inner support, A.

The rings B are secured to the frame A in such manner as to be eccentricwith the axle, the greatest point of eccentricity being in front of theaxle, or at a point aligning horizontally the position the paddlesassume when passing downward to the water.

Instead of the slots a a being out in the ships hull when the wheel isin position at the side,

the said slots may be cut in a timber secured to the hull.

The axle A of the wheel, within the frame and near each end, is providedwith integral hubs H, in which are secured a number of carryingarms, H,equal to the number of paddles to be placed in the wheel. The arms H,radiating from the hubs,are curved at apoint,preferably above theircenter, in the direction in which the wheel is intended to move whenpropelling the vessel forward, as shown in Fig. 1, each arm beingprovided with an eye in the end.

The ring B is provided with an inwardlyextending fiange,m,as shown inFig. 3, adapted to receive a collar, M, having a recessed inner face anda series of equidistanced peripheral slots, 777,, equal in number to thenumber of arms H, and adapted to be positioned in substantial alignmentwith said arms. To the inner surface of the collar M, within the recessin", aseries of rods, N, are secured,which rods project up through theslots m, and, curving inward to the rear of the arms H, have their endsbent at right angles, also inward.

The paddles N, which may be made as broad as desired-say five or sixfeet are made with a front and rear concave surface, a n, and of greaterthickness upon one longitudinal side, 00?, than the other, asillustrated in Fig. 1, the said thick edge being chamfered ofl' upon therear side at the ends to permit perfect freedom of play when pivoted tothe arm H.

Upon the rear of each paddle, centrally the same and near the ends,posts 0 are secured, having inwardly-extending opposing pins 0 and anaperture, P, near the end. To place will be made concentric with theaxle.

the paddles in position, the arms H are brought down to a substantiallyvertical position and the paddle is placed transversely the frame, faceout and heavy end up. The pins 0 are then made to enter the eyes in thearms H and secured in position by nuts or other suitable means. Theangular ends of'the rods N are then passed through the apertures P ofthe posts and secured therein similar to the pins 0'.

The paddles may be more or less boxed along their thick side andpartially at the ends, so that by manipulating the lever E the ring BThe brackets will thereupon lift the water, and in a stern wheel throwthe same over the deck, which in the event of firewill materially aid inextinguishing the same. i

It will be observed that the paddles enter the water in an almostvertical position and pass out therefrom in substantially the sameposition.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination. with the axle A, carryingcurved arms H, and paddles N, provided with a concaved front and rearsurface and one weighted longitudinal edge pivoted to said arms, ofeccentric rings B, collars M. sup ported by said rings, and curved barsN, radiating from said collar and pivoted to said paddles above saidarms,substantially as shown and described, and for the purpose hereinset forth.

2. The combination, with the axle A, carrying curved arms H, and paddlesN, provided with a concaved front and rear surface and one weightedlongitudinal edge pivoted to said arms, of the eccentric rings B, acollar, M, supported by each of said rings,provided with o a recessedinner face, 111?, a series of peripheral recesses, m, and a series ofcurved rods, N, attached to said collar, passing through saidrecesses,and pivoted to the paddles above the arms H,substantially asshown and described.

3. The combination, with the axle A, provided with integral hubs H,having attached thereto a series of curved carrying-arms, H, and paddlesN, provided with concaved front and rear faces, a weighted longitudinaledge, and posts O,'attached to the rear face, provided with apin, O, andaperture 1?, of the eccentric rings B, a collar, M, supported by saidrings, provided with a recessed inner face, on", a series of peripheralrecesses, m, and a series of curved rods, N, attached tosaid collar,passing through said recesses, and pivoted to the paddles above the armsH, substantially as herein set forth.

4. The combination,with the frame A, provided with aligning recesses aa, the axle A, carrying curved arms H,and paddles N,piv oted to saidarms, of the eccentric rings B, provided with aligning pins 1) b, acollar, M, supported by said rings, curved bars N, ra- 6 diating fromsaid collars and pivoted to said paddles above saidarms,the slottedhorizontal bar D, and lever E, all arranged to operate substantially asherein set fort-h.
